How will the four piles of earth spheres interact during a volcanic eruption (looking for sphere-sphere interactions during the eruption, not the ones that cause it)? Thank you ahead of time:)

google my dude. if it doesn't show up ask me.

i would say it is

the species living around the vents are especially good at dispersal.  

deep-sea vent originates on the floor of the ocean when seawater circulates through hot volcanic rocks, usually situated where the new oceanic crust is being produced.  

biological dispersal refers to the movement of species from their location of birth to their site of breeding, or from breeding site to another. similarly, the oceanic dispersal refers to the movement of the species from one land mass to another by sea crossing.
